Fast, Reliable Custom & Geometric Windows Across Kendall
Custom and geometric windows in Kendall run $900-$1,800 per opening for a standard impact-rated unit, and $2,500-$5,000 for large arched or custom-shaped openings that require structural work. Those numbers reflect something most window companies won’t tell you until they’re standing in your living room: the original openings in Kendall’s 1970s-1990s CBS ranch homes are frequently out of square, and the job often turns into a frame-modification project before the first window is even ordered. We’ve been doing this work in Kendall long enough to price it honestly up front, not after we’ve cut into your stucco. Call (863) 862-5435 for a free in-home measure and a written quote that accounts for what’s actually behind your wall.
Ed Winslow’s name is on the door, and on every job we do. Kendall homeowners call us because we answer the phone, show up when we say we will, and don’t hand off the hard parts to a sub crew we’ve never met.
Why Winslow Windows & Doors Is Kendall’s Preferred Custom & Geometric Windows Company
Winslow Windows & Doors has been locally owned and owner-operated since 2011, and we work across Kendall every week. The homes here tell a specific story: concrete block and stucco construction, original aluminum single-pane windows, and openings that settled out of square decades ago. A national chain’s install crew might not recognize a rotted wood buck behind a 1983 jalousie frame. Our crews do, because they’ve opened up hundreds of Kendall walls just like it, and we also bring deep experience in Shingle, Tile & Metal Roofing - Kendall homes.
We are an authorized installer for PGT, CGI, CWS, and ViewLux, among eight premium brands. Every technician who arrives at your Kendall home is background-checked and in uniform, so you know exactly who is walking up your driveway. And when you call, a live person answers. Not a voicemail loop, not a call center in another state. That matters at 2 a.m. during storm season and it matters at 9 a.m. when you just want a straight answer about your jamb depths.
We back every installation with the 36500-Day Done Right Promise. If it’s not done right, we make it right. Period. No fine print, no chasing a warranty department. You call the same number, and we come back.
Our Custom & Geometric Windows Services in Kendall
Every Custom & Geometric Windows job in Kendall starts with the same question: what’s actually framing that opening? We inspect before we quote, because the answer changes the price and the permit. Here’s what we handle across Kendall:
Custom Impact Windows
All of Miami-Dade County sits inside the High Velocity Hurricane Zone, so every custom window in Kendall must carry a Miami-Dade County Notice of Acceptance. That’s not optional and it’s not an upsell. We size and order impact-rated units matched to your opening, your wind zone, and your design pressure requirements. A ranch home on Kendall Drive near SW 97th Avenue meets the same HVHZ standard as a condo in Miami Beach, and we price the work accordingly. For homeowners also considering exterior upgrades, our Roof Replacement & Installation - Kendall team coordinates seamlessly with window projects.

Geometric & Shaped Windows
Triangles, pentagons, trapezoids, half-rounds. Kendall’s older ranch homes were built with rectangles, and homeowners who want a geometric statement window are usually adding something the original framing never anticipated. That means custom shimming, extended jambs, and often a new header. We measure the opening, not the old frame, and order the unit to fit the true rough opening plus the modifications we’ve already scoped in the contract.

Arched & Curved Windows
Arched windows in Kendall often tie into barrel-tile entries or mission-style facades, and they fail differently than rectangles. The arc creates a water-shedding sweet spot where missing flashing or a backwards slope sends afternoon storm water straight behind the stucco. We reframe the jamb and header as needed, slope the sill pan correctly, and flash the full perimeter before the new unit goes in. This is the difference between a window that lasts 30 years and one that stains your interior wall by next summer.

Oversized Openings
Floor-to-ceiling picture windows, wide sliding sight lines, and open-corner installations all require structural review. Original 1970s headers in Kendall were not engineered for today’s HVHZ wind loads, and we routinely pull permits and install a stronger header before hanging a large-format impact unit. That inspection and allowance process is built into our written quote, so you’re not absorbing a surprise change order mid-install.

Trusted Brands We Service in Kendall
We install and service windows from PGT, CGI, CWS, and ViewLux, and we’re an authorized installer for all four. That authorization matters in Kendall because local code compliance rides on Miami-Dade NOA documentation that must match the exact configuration of your unit. We keep the paperwork straight and we know which products meet which wind speeds and design pressures for your specific address. Custom geometric units from PGT and ViewLux tend to lead the Kendall market for shaped openings, and we order them weekly for homes across the area.
We also stock common components locally, so a blown seal or a broken balance doesn’t leave you waiting on a slow parts chain when you call us. Fast turnaround is part of being the local option.
Common Custom & Geometric Windows Problems We See in Kendall Homes
- Out-of-square openings from settled CBS block. Kendall homes built in the 1970s and 1980s often have rough openings that are 1/4 to 1/2 inch out of square. A standard retrofit window can’t absorb that, so the job requires custom shimming, extended jambs, and sometimes planing the buck. Bad installs here leak before the next afternoon storm.
- Undersized headers from original construction. A 1976 ranch on a quiet Kendall street was framed with the lightest header the code allowed at the time. Put a large geometric impact unit in that opening and the header deflects under wind load, cracking the stucco around the window within a season or two. We inspect for this every time.
- Rotted wood bucks and corroded jambs behind aluminum frames. Decades of humidity and storm-driven moisture have done their work behind the original aluminum frames. We’ve opened Kendall walls to find wood bucks soft enough to push a screwdriver through by hand. You can’t hang an impact window on that, so reframing becomes part of the job.
- Failed sill pan waterproofing on arched openings. Kendall’s near-daily afternoon storms find any flaw in the slope or flashing of an arched window. Water intrusion behind stucco shows up as peeling paint, mold, and eventually rotted framing. Our replacement process includes full sill pan and flashing work, not just swapping glass.
Pricing for Custom & Geometric Windows in Kendall, FL
Custom and geometric window work in Kendall is priced like what it actually is: a structural and code-driven installation, not a retail swap. Standard impact-rated rectangles run $900-$1,800 per opening installed. Arched and curved units typically land between $1,800 and $3,500 depending on arc radius and frame material. Large or oversized openings with header reinforcement run $2,500-$5,000. Whole-home packages across a four-bedroom Kendall ranch start around $8,000 and can exceed $25,000 for large custom glazing and multiple shaped units. What moves the price: opening count, wind zone, floor height, frame material, and how much reframing your specific openings need.
We give you a free in-home measure and a written, line-item quote before you sign anything. No allowances that balloon later. If we find rotted framing or an undersized header during the measure, it goes in the quote. If we find something unexpected during install, we stop, show you, and get written approval before touching it. Call (863) 862-5435 to schedule your free estimate.
What Custom & Geometric Windows Costs in Kendall
Here’s the honest range for what our Kendall customers actually pay, based on the homes and openings we see every month. A standard impact window in Kendall runs $800-$1,500 per unit installed. Impact single-hung windows land between $900 and $1,800. Large custom openings, arched units, and geometric shapes run $2,500-$5,000 per opening because they almost always require structural modification. Whole-home packages across Kendall’s typical 3-4 bedroom ranches run $8,000-$25,000+. The biggest single variable is what’s behind the existing frame. An out-of-square CBS opening or rotted wood buck adds framing work that a big-box quote won’t include but our written estimate will. Frame material matters too: aluminum is lighter and less expensive, vinyl handles humidity well, and premium aluminum or thermally broken frames add cost but stretch the unit’s lifespan in Kendall’s climate. We measure, inspect, and quote free. You’ll know the real number before you commit.
Florida Pays You Back
Kendall homeowners can stack real incentives on custom and geometric impact window work, and we walk you through each one without overpromising. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact windows are exactly the kind of project the program targets. Florida also exempts impact-resistant windows and doors from sales tax. On the federal side, the 25C energy credit returns 30% of the product cost on qualifying units, up to $600 per year. And after a wind-mitigation inspection (typically $75-$150 in Kendall), homeowners regularly see around a 25% reduction on the windstorm portion of their premium. Your carrier sets the final number, and program funding changes, so we never guarantee a payout. But the stack is real, and a properly documented Miami-Dade NOA installation is the foundation for claiming every dollar.
One comparison worth making before you decide: impact windows versus hurricane shutters. Shutters are cheaper up front, but you’re hanging and removing panels before every storm, storing them the rest of the year, and hoping the hardware is in good shape when a warning hits. Impact windows are permanent protection, no panels to deploy, and they work every single day of the year for UV, noise, and energy efficiency too. For Kendall’s daily afternoon storms and year-round sun, we think the math favors glass. We do not sell or install shutters, so our opinion is based on what we see fail on Kendall homes, not what we’re trying to sell you instead. Many homeowners pair their Impact Windows in Kendall with full exterior protection packages.

FAQs - Custom & Geometric Windows in Kendall
Yes. Every window in Kendall, regardless of shape, falls under Miami-Dade County’s High Velocity Hurricane Zone requirements and must carry a Miami-Dade NOA matched to the specific configuration. An arched or geometric unit has to meet the same design pressure and wind speed thresholds as a standard rectangle, and the manufacturer’s NOA must list that exact shape. Call (863) 862-5435 and we’ll verify the NOA for your specific opening before you order anything.
You can’t get a direct jalousie replacement that meets HVHZ impact standards. What we do instead is remove the old jalousie hardware, reframe the opening with proper depth and a square rough opening, then install a custom impact window built for that opening. The original jamb depth rarely works because jalousies are thin by design, and impact units need more frame depth. We handle the framing as part of the install and quote it up front.
The most common triggers are header sizing, wall bracing, and electrical. Original 1970s and 1980s headers in Kendall are often undersized for today’s HVHZ wind loads, so a large geometric window usually requires a stronger header. Opening a CBS wall can also expose wiring that must be rerouted or brought to current code. We pull the permit, coordinate the inspection, and build these costs into the written quote before work starts. If an inspector flags something we didn’t anticipate, you approve the change in writing before we proceed.
Yes, meaningfully. Original single-pane aluminum windows in Kendall leak conditioned air and transfer heat directly through the frame. Replacing them with energy-certified impact windows typically cuts the solar heat gain dramatically, and Kendall’s year-round cooling load means you feel that difference on your FPL bill every month. The exact savings depend on your home’s orientation and the glass package you choose, but our Kendall customers report noticeable reductions, especially on west-facing walls along major corridors like Kendall Drive. We’ll recommend the right glass package for your exposure during the free measure.
If your current window sticks, binds, or has visible gaps between the frame and the stucco, the opening is likely out of square. In Kendall’s CBS homes, 1/4 to 1/2 inch of drift from settlement is common and entirely workable with custom shimming and extended jambs. The concern isn’t whether it’s out of square, it’s whether anyone measured it before ordering your window. We measure every opening’s true rough dimensions and diagonals during the free estimate, and the quote reflects exactly what the framing needs. Call (863) 862-5435 to have a real installer put eyes on your walls, not a salesperson with a tablet.
